IRIDIUM SATELLITES

The Iridium satellite constellation is a system of 66 active communication satellites and spares around the Earth. It allows worldwide voice and data communications using handheld devices. The Iridium network is unique in that it covers the whole earth, including poles, oceans and airways. The satellites used are frequently visible in the night sky as short-lived bright flashes, known as Iridium flares. The Iridium satellites orbit at an altitude of approximately 483 miles above the earth (and travel at approximately 16,689 mph resulting in a complete orbit of the earth approximately every 100 minutes).
